Greater foxtail is the first grass species to initiate the period of grass pollen allergy, hay fever-like symptoms due to pollen or pollen from grasses in the air. The cigar-shaped spikes can now be seen everywhere in grasslands and on roadsides. In addition, the necessary other grass species are now also flowering, such as Crocus, Thin Dravik, Fescue and in the south also Gloss Oats. The 2 million people who react to grass pollen with hay fever-like symptoms notice this all too well.
